Choice of quenching temperature and its effect on the structure and properties of a high-strength grade 01979 aluminum alloy

详细

Differential scanning calorimetry data are presented for the 01979 alloy produced by granular technology. The optimum quenching temperature is confirmed. Strengthening phases dissolve most completely at this temperature. The phase composition of the high-strength aluminum alloy is studied using scanning microscopy and electron microprobe analysis. The AlCu₄, AlCr₂, and MgZn₂ phases and their interplanar spacings are determined.
